With a tandem axle you can add up to 3 crossmembers, but the number you choose would be yours to determine. If you take your RV off road, you may want all 3, if you’re only driving on highways, 1 would probably be sufficient but again, the amount would be yours to decide in the end.
For the fitment of the crossmember, you will need a straight, clear shot between the frame hangers, unfortunately we can’t determine this by the year/make/model of your unit you would need to check for that clearance. ( Morryde International. Inc)
